项目摘要

The doctoral research is linked to the EPSRC funded project PhysiCAD which is investigating a tangibleinterface for CAD using construction kits. The PhysiCAD project has revealed three areas of possibleresearch:1. Evolving construction kits for engineering design supportUsing Lego as a starting point (chosen for its familiarity and accessibility) the aim is to develop asystem that allows evolution of the components to meet the user's requirements and the needs of thedesign process. The limitations of Lego for design - resolution, scale, surfaces, and functional parts - need to be investigated. From this, a syntax for evolutions needs to be developed to allow users tocommunicate their required changes given the stage of the design process.Novel brick types (compatible with Lego) - flexible, off-plane, functional, higher resolution - must bedesigned to accommodate the evolutions of the construction kit as well as methods to generate bricksand systems of bricks to support the designer and design task.2. Techniques for simultaneous localisation and mapping of constructed models to useful CAD modelsThe first part is to explore and develop approaches for localising components within a constructedphysical model. Current approaches to consider are: IMUs embedded in Lego bricks, Computer visionsystem using a Kinect Sensor, Construction motion of the user's hands/arms. An experimental rig forthe IMU technique is currently in construction. A preliminary scoping study has been performed usinga computer vision approach.A method of translating the chosen SLAM technique into a useful CAD model or 3D visualisationneeds to be established. Potential expansion should include displaying changes in the digital modelon to the physical one as well as methods for feature based construction.This would provide an intuitive, tangible for creating digital models - moving away from the high skilllevel required for CAD using a keyboard/mouse/screen.3. Digital-Physical construction kits to support co-design and co-creationAn important aspect of physical prototyping is the ability to collaborate and communicate over thesame model. However, the affordances of digital modelling are lost when using a physical modelalone. A novel system to combine the two mediums is to be explored. Design behaviour comparisonbetween individuals, pairs and groups shall be investigated to establish requirements and developfunctionality of the system.This work would lead on from the PhysiCAD development rig - using a top down projector to augmentthe communal workspace. Means for capturing and presenting rationale, constraints and past andpossible design iterations will be explored.One of these three areas will be chosen following the initial scoping and exploratory phase of theresearch.

该博士研究与EPSRC资助的PhysiCAD项目有关，该项目正在研究使用建筑工具包的CAD有形界面。PhysiCAD项目揭示了三个可能的研究领域：1.不断发展的工程设计支持建设套件使用乐高作为一个起点（选择其熟悉性和可访问性），目的是开发系统，允许组件的演变，以满足用户的要求和设计过程的需要。乐高设计的局限性-分辨率，规模，表面和功能部件-需要调查。因此，需要开发一种演化的语法，以允许用户在设计过程的各个阶段交流他们所需的更改。必须设计新的砖块类型（与乐高兼容）--灵活的、离面的、功能性的、更高的分辨率--以适应建筑工具包的演化，以及生成砖块和砖块系统的方法，以支持设计师和设计任务。技术的同时本地化和映射构建的模型，以有用的CAD modelsThe第一部分是探索和开发的本地化组件在一个constructedphysical模型的方法。目前考虑的方法有：嵌入乐高积木的伊穆斯，使用Kinect传感器的计算机视觉系统，用户手/手臂的构造运动。惯性测量单元技术的实验装置目前正在建设中。一个初步的范围研究已经进行了使用计算机视觉的方法。一种方法，翻译选择SLAM技术到一个有用的CAD模型或3D可视化需要建立。潜在的扩展应该包括显示数字模型到物理模型的变化以及基于特征的构造方法。这将为创建数字模型提供直观，有形的方法-远离使用键盘/鼠标/屏幕的CAD所需的高技能水平。3.支持共同设计和共同创造的数字物理构建套件物理原型的一个重要方面是能够在同一模型上进行协作和通信。然而，当单独使用物理模型时，数字模型的启示就消失了。一个新的系统，联合收割机结合这两种媒体是要探索。应调查个人、成对和小组之间的设计行为比较，以确定系统的要求和开发功能。这项工作将从PhysiCAD开发平台开始-使用自上而下的投影仪来扩大公共工作区。捕获和呈现原理，限制和过去和可能的设计迭代的方法将被探索。这三个领域之一将在研究的初始范围和探索阶段之后被选择。
